4x23 - Law & Order: Criminal Intent

It's open season in New York when not one but two powerful judges are executed. At first they seem to have no connection; one was a family court judge whose entire family was attacked, the other is an appellate court judge. After investigating the judges more thoroughly, Goren and Eames realise that their first set of suspects was simply a smokescreen, and there is a far more insidious threat. Their investigation leads them to a non-custodial father who has a beef with the court system.
